I always seemed to call pokemon by there real names... well, except once, I had trouble pronouncing Rattata, I said Ra-ta-ta-ta, whit there are not that many ta's...
That, and when Gardevoir came out, I was only a kid, so I would say Gar-de-voi-er..Emphasis on the voi...
Fun Fact: Pokémon is pronounced: Po-Kay-Mon
The e with an accent mark above it, it is a french letter... it is pronounced AY, r simply, a long A sound.
Another thing, my sister pronounces Palkia, as Pal-Kia, when it is pronounced Paul-Kia, with an AW sound.
